应用黑油模型计算油气藏过渡带油气地质储量

CALCULATION OF OIL AND GAS GEOLOGIC RESERVES IN THE TRANSITION ZONE WITH BLACK OIL SIMULATOR

确定油藏过渡带的流体饱和度，是准确计算非均质、低渗透油藏中油水过渡带油气地质储量的关键。通过调整毛管压力曲线确定含油饱和度分布，并应用引进的黑油模型，对夏子街油田三叠系克拉玛依组油藏过渡带的油气地质储量进行了计算。该方法与常规方法相比较，具有准确、方便、分层灵活等特点。

The calculation of fluid saturation in the transition zone is highly related to accurate calculation of oil and gas geologic reserve in oil/water transition zone in heterogeneous low permeability reservoirs. The distribution of oil saturation is determined by modifying the capillary pressure curves, and oil and gas geologic reserves in transition zone of Triassic(Karamay formation) in Karamay oilfield calculated with the introduced Black Oil model. Compared with the conventional method, this method is more accurate, simpler, and more flexible in layer division.
